vices of this class that are designed particularly for illuminatingpurposes, the specific kind of burner being that commonly known asinstantaneous, and designed for the consumption of the lighterhydrocarbon oils, of which gasolene is a type, although heavier oils,such as kerosene, may be used with like efficiency, owing to certainnovel features embodied in my device.

The chief objects of the improvements which constitute the subjectmatter of this application for patent are :--to provide a burner of theclass stated that will give a light of high efficiency with aneconomical expenditure of fuel, and to produce an illuminating apparatusin which hydrocarbon oils of varying specific gravity may be efficientlyburned.

Referring specifically to the various advantages due to the novelconstruction of the device hereinafter described, it should be notedthat provision is made for retaining the heat in the burner body whenthe flame is turned low, thus insuring a sulticient local temperature toprevent the extinguishing of the flame from radiation under the givenconditions, the retained heat being adapted to produce a constantreserve supply of as may be necessary for the pro duction of anilluminating flame.

Other objects of importance are :-the introduction of a mixer of novelform that will insure a proper commingling of the air with the fuel gas,and to furnish a construction that will safeguard the oil filteringmaterial by confining it to a portion of the oil passage that is notmaterially affected by the heat convection, thus prolonging theefficiency of the burner, and avoiding ClGtGllOlt tion which may resultby the slow combos tion of the substance used for filtering or strainingwhen subjected to long continued heat.

Another object of considerable moment is to produce an arrangementwhereby the stem of the regulating valve may be given Specification ofLetters l-Patent.

more than one complete turn, thus permitting the use of a fineradjustment of the said valve than when limited to the fraction of aturn. As a further improvement, I have brought the stem of thestop-valve to a position where it may be within easy reach of theoperators hand.

I accomplish the desired results by means of the apparatus illustratedin the accompanying drawing which forms a part of this application, theimportant details of the construction and manner of assembling thecooperating parts being disclosed in the fol.- lowing v1ews:-

Figure 1 is a side elevation, partly in section, of an instantaneouslamp embodying my improvements; and :-Fig. 2 is a fragmentary viewshowing the body of the burner and attachments, the said burner and hoodand also the mixer being in section.

Referring to the details of the drawing, the numeral 5 indicates asupply pipe for the fuel oil, having threaded connection with one end ofa coupling 6, the opposite end of the latter comprising a valve casing7', in which is a shut-off valve of usual construction, not shown, sinceit forms no part of the present invention. The said coupling is providedwith a nipple 8, threaded so as to adapt it to be attached to anyconvenient source of fuel supply. Immediately below the coupling 6,surrounding the said supply pipe 5 and adjustably supported thereon by acollar 9, is a globe support consisting of a cylindrical body 10,suspended by hangers 11 from a concave top plate 12 secured to saidcollar, and having a flarin skirt 13 provided with the usual. globeholding screws 1.4, Upon the supply pipe, a suitable distance below thesaid globe holder, is mount ed a burner, comprising a hollow body 15bell shaped and preferably cast with comparatively thin walls andforming a shell. The supply pipe passes entirely through this burner orshell, suitably threaded. holes being provided for this purpose in theshell walls, and the lower portion of the pipe is correspondinglythreaded as indicated at 16.

The burner body 15 is provided with a hood 1.7, having a contourcorresponding to that of the body, and is provided with an aperture 18to permit to he slipped over the supply pipe '5, and when in position,the hood is supported upon the upper end of the body with its wallsspaced away from the outer surface of the burner thus leaving aninterval 19 between said hood and body to provide an air space.

The lower extremity of the pipe 5 communicates with a horizontalconnection 20. which in turn, connects with a short vertical pipesection 21 which is provided with a regulating needle valve (not shownin detail) of usual type. The stem of this regulating valve extendsdownward for a suitable distance where it terminates in a button 23,having a designating character 2% thereon. Upon the stem 22 of theregulating valve is adjustably mounted by a set screw, a stop finger 25which is adapted to engage the connection 20 in the manner shown ata,the adjustment permitting the said stem to be given any number of backturns desired, since one revolution will suffice to retract the stem tosuch an extent that the finger will clear member 20. Above theconnection 21, and in axial alinement therewith, is a pipe 26 ofsomewhat larger cross diameter than the said. connection and samecommunicates at its upper end with the cavity of the body 15. The pipe26 and the connection 21 are slightly separated at their adjacent ends,and between them is inserted a box forming a gas and air mixing chamber.This box consists of a short section of rectangular tubing open at theends, and placed transversely to the pipes which it connects, the endsof the pipes 21 and 26 passing through suitable holes in opposite sidesof same.

The body 15, is provided with ordinary pendent burner tips 28 adapted toreceive standard mantles shown in dotted outlines 29, said tips beingconnected to the said shell or body 15 by suitable threaded nipples 3Ocommunicating with the interior of the body.

To provide a suitable strainer or filter for the oil, to prevent foreignparticles from being carried to the burner, the upper portion of thesupply pipe is filled with a section of cylindrical wick 31. This wickextends from the vicinity of the coupling 6 to' the upper part of theburner, and to maintain the same in position, a supporting wire or stop32 is inserted in said tube below the wick.

The stop-valve located in the valve casing 7, is furnished with anelongated stem 35 which passes down through the globe holder parallelwith the supply pipe 5, and terminates in a button or handle 23*, as inthe case of the regulating stem, and likewise has a designatingcharacter 24*. Extending downwardly from the burner body 15 is a wire 34terminating at the lower end in an eye 35, arranged a little below thelevel of the branch 20. The purpose of this wire eye is to serve as asupport for a torch which is used to afiord a preliminary heating of thebranch and lower end of the supply tube sufficient to produce gas forstarting the apparatus, such torch not being shown as it is a commonexpedient in all lamps of this class.

The operation of the apparatus is as follows :Connection having beenmade with a source of oil supply, the stop-valve in 7 is opened byturning the handle 28 the oil. will then flow down the supply pipe 5,and after passing through the filtering material 31, will fill thebranch 20 and section 21 and lighted torch is then applied so that it isbelow the branch 20. The regulating valve in 21 is then opened, and whenignited, the oil in the adjacent passage will become gasified and passupwardly through the mixing chamber 27 into the pipe 26, from whence thecommingled gas and air will enter the burner body 15 to be distributedto the coinmunicating burner tips 28. After the lamp has been started inthe manner described, the stop-valve is allowed to remain open and theflow of gas controlled entirely by means of the regulating handle 23.Thus, when it is desired to reduce the light, the regulating valve stemis turned to the right until contact is made by the stop finger at thepoint a on the connection 20. This is so arranged as to prevent thecomplete closure of the said regulating valve and will there fore permita slight and constant flow of gas to the burner. The air within thespace 19 between the burner and hood will be heated, and as it ispartially confined by the overhanging hood walls, it will act, inconjunction with the adjacent members, to maintain the gas in the burnerchamber at a proper degree of heat for combustion, though a very slightflame will be maintained at the burner tips. When it is desired toincrease the illumination, it is only necessary to turn the regulatingvalve stem tothe left to retract the valve and thus allow a largeramount of gas to flow to the burner body.

The limitation of the strainer to a positionin the upper portion of thesupply pipe will prevent undue heating of the wick and the consequentcharring and deterioration of the substance composing same.

The heat in the burner body surrounding as it does the supply pipe 5 foran appreciable portion of its length, tends to gasify the fluid in saidpipe more effectively than would be possible if said pipe was not thuslocated.

Having thus described my invention what I claim as new is 1. In ahydrocarbon lamp, the combination with a burner consisting of a shell,mantle-supporting means depending from said shell and a hood inclosingsaid shell on the top and sides and in close proximity thereto, meansfor conducting gas to said shell, said means comprising a fuel-supplypipe, a mixing chamber communicating with said pipe and the atmosphereand arranged below said burner, a valve controlling said mixing chamberand a valve controlling said fuel-supply pipe.

2. In a hydrocarbon lamp, the combination with a fuel supply pipe, valvecontrolling said pipe, a strainer arranged in the supply pipe, means forsupporting the strainer in operative position in said pipe, a mixingchamber communicating with the supply pipe" and a valve regulating theflow of oil to said chamber, a burner comprising a hollow shellsurrounding the said supply pipe and in communication With the mixingchamber, and a hood covering the top and sides of said shell andconforming to the shape thereof, the Walls of the hood being spaced fromthe shell to form a restricted air space closed on the top and sides.

In testimony whereof I altix my signature in the presence of twoWitnesses.
